...but I figured out why I prefer .45 over 10mm. Primarily because I don't own a 10mm and never have. Didn't realize I owned any 10mm ammo either, but somehow one got mixed in with some .45 stuff I took to shoot today. I'd had this happen once with a .40 round, and had never owned one of those either. The .40 round fed out of the mag, and the slide travelling forward pushed it right out the end of the barrel.

The 10mm round today came out of a Freedom Munitions box of their "reman" ammo. It chambered but didn't fall through. The misfire made me stop and look, and the primer had a very slight dent. No clue how I've ended up with odd ammo mixed in, but I've spent the afternoon sorting and checking all my centerfire ammo.

I was preoccupied with setting up targets, raking leaves to make it easier to find brass and trying to get some shooting in before the rain. Which means I wasn't paying attention, in my rush to load mags. A different combination of calibers could undoubtedly have much more serious consequences.

So yes, I like .45 a lot better than 10mm when I'm shooting a .45
 
It would have been a lot safer to have had a 45 round mixed in with 10mm. It wouldn't come close to chambering. How did you miss that when loading the mags? In fact I'm surprised the feed lips were close enough to let it stay in the magazine.

Not sure how I missed it. We'll, I am sure....slid the box open just far enough to dump 5 out in my hand and loaded them in the mag, then dumped 2 more and loaded them. The 10mm just happened to be the last one in/first out in that mag. It was almost the same exact OAL, same color (factory reman, mixed stamp) and my attention was on everything except the ammo I was putting in the mags.

It happens.

There are somewhere around 8 billion people on this earth.

Name a mistake, and it's happening right now.

My FiL and I usually take about six guns apiece when we go shooting.

I messed up once and tried to load a 45acp cartridge into a 40 S&W magazine, and it (obviously) wouldn't fit.

My FiL managed to load a 380acp cartridge into a 9mm service pistol.

It chambered and fired, but he had to take it home and fool with it to remove the jam.

Stuff happens. Now I only keep one caliber of ammo on top of the shooting bench.

I've had no mistakes since I instituted that rule, but doubtless I'll mess up again eventually.

Kind of like the monkey typing Shakespeare...

... give me tens of thousands of transactions, and I will make an astonishing mistake. :)
 
The 10mm really comes into its own for me with full(ish) power ammo and ranges over 25yds.
I really enjoy my 10 running 180s at 1200 (which cheap S&B ammo actually does from its 6" barrel) when shooting random range stuff, or rifle gongs out beyond 50yds.
With my 45 and 230s at 800ish (5" Xdtac) it was pretty loopy, If I'm remembering correctly I used a half front sight above blade hold.
The lag between boom and thump was always fun tho.

Ive also done the .45 SUPER with 230s at 1250, and from that XD (after mods) they weren't really fun to shoot for more than a mag.
200s were much more controllable, but still, if I'm dropping that much weight might as well shoot a 10......Course I still have 50rnds of the super ammo on my ammo shelf. Just need another hand cannon to fire it.
 
We had a customer bring his Kimber in for a barrel replacement because he thought the chamber had enlarged somehow. He showed me the fired case that looked like a pregnant guppy. It was a .40 that had gotten in his stuff somehow. He'd loaded it along with a magazine of .45 acp and evidently the extractor held it against the slide face tight enough to fire.
Had another bring in a 9mm magazine stuffed full of 40s.
Add in the four customers over the years with 9mm cartridges jammed backwards into the chamber and you begin to believe there is no limits to mistakes that can be made.
 
I have never owned or shot a 10mm. I did once fire a 9mm in a .40 caliber pistol. The shot sounded a lot quieter & the bullet hit to one side of the target. I honestly can't remember now if the case ejected or what. It happens.
 
Unlike the OP I have both.
These are all 45 acp

Four 10mms and a 9mm

45 acp pro: more commonly available, bigger bullet, comparatively softer shooting
10mm pro: additional round of capacity in 1911 format, generates greater energy, most HP bullets will expand at 10mm velocity
 
As an instructor I used to see 9mm loaded in .40 S&W guns on occasion, even though the two types of ammo were on tables 40 feet apart from each other. The 9’s usually fired in the Glock .40s. If it hit the target it keyholed.
 
I bought a box of Blazer Brass 9mm at a range one day to shoot in a 9mm that I rented. The rule was that one must only shoot range ammo, ammo they would sell you, in their rental guns. I did not blame them there. Makes sense.
Anyway, I loaded the magazine of the S&W Shield I was trying out and the first round fired but the slide didn’t fully cycle. The case of the fired round was inside the chamber. That case was a .380. The Mag as loaded with .380’s. The entire box of ammo was .380 ACP.

The range master swore that no one had swapped the ammo tray from a 9mm to .380 box and vice versa. We went through his Blazer Brass ammo boxes but found no 9mm in a .380 box. Anyway, it was a funny event. No harm done.
 
10mm may have too much horsepower for town living.. I carried one for 20 years on the ranch after leaving LE. I once knocked a coyote flat at 80 yards. Shot a road hit antelope in the back of the head from about 30 yards and popped both eyes out of their sockets.. Put several 900 lb cattle down that had life ending injuries..

Parked the 10's when I moved to town and went to 45ACPs.. Less recoil, muzzle blast, and over penetration worries.. The 10's are still my favorite pistol cartridges though.
 
I may have to put a 10mm on my wishlist in the near future. It seems like it would be a pretty good round with some usefulness in hunting. It's just fascinating how ammo I've never bought for guns I've never owned ends up mixed in with factory .45 ammo. Maybe a sign that I'm supposed to own them?
 
In 10mm threads fair chance someone posts the incorrect blanket generalization that 10mm is overpenetrative.
Lets mythbust that in advance.
10mm is not overpenetrative with the right bullet (same can be said for 9mm and 45 acp).

Another example, this one also preempts an attempt to discredit the prior examples as not "full power" and therefore not valid: :neener:

You like .45 more than 10mm because you put some 10mm in your .45 magazine and didn't know and had to stop shooting to clear the chamber?

I take it you don't like .45 Super then because if one of those got into your .45 ACP, especially a 1911...

It was kinda tongue-in-cheek. I don't like 10mm in my .45acp.
 
This is why I don't buy .380 pistols. Trying to avoid ammo mix-up with 9mm.

BTDT, with a 40S&W in a 45ACP mag, once, just never loaded the mag into the gun.
 
10mm has won me over BIGTIME
If youre a handloader, the reasons are obvious.
10mm can be loaded down to 45ACP performance and accuracy. Also chambered in the same platforms. Also can load 10mm to almost double the power of 45 If you so desire. It probably has to do with the 21,000psi 45ACP to the 10mms 37,500psi abilities. If youre a hunter of any game animals, this is an entire world of difference.

Now, 10mm is currently less common than 45ACP, so finding and keeping an ample supply of Brass is the biggest challenge for a handloader (or any component in this day and age for that matter)
If i did not handload my own, I would consider this quite a bit differently.

45 ACP was developed about 115 years ago.
The 10mm came out about 80 years later. This comparison is not and shouldnt even be a fair comparison because it is not Apples to Apples.

Is Tiger Woods a better golfer than Jack Nicklaus?
Yes. But .........
 
This captures my position as well; I'm a YUGE 10mm fan:
